Supervision, control and maintenance support in served environments
Highly served entities like rail networks and gas pipelines require the ability to interconnect the elements of various subsystems via WAN, linking the various geographically dispersed sites or stations.
The SAM system responds to this need by providing interfaces for different technologies suitable for managing information in different geographical areas.
Some supported WAN technologies are:
Managing large volumes of data
- G.703: E1 flows suitable for transport over SDH
The size of complex systems like railway networks or hospitals, where hundreds of objects must be continuously monitored and/or controlled for proper operation of the system, requires the use of suitably sized hardware/software to meet the performance demands. The SAM system provides for the collection of all data generated by the different supervised or monitored objects to one or more central servers that organise, process and structure the information.
Being a modular system, the hardware that will manage the information in the database will be appropriately sized to properly handle the data processing.
Availability and Reliability
The SAM system offers various solutions for optimising reliability and therefore system availability:
- Redundant central servers
- Database backup systems
- Redundant gateway resources
In some contexts it may be necessary to install gateways - which must be connected to the equipment to be supervised - in industrial environments, or in any case not adequately protected against external agents like dust or temperature fluctuations.
The SAM system responds to this need by offering a range of equipment suitable for industrial environments, with different protection levels and operating in a wide range of temperatures.
The speed at which today's technologies evolve and adapt to continuously new market demands calls for constant updating in terms of protocols and systems supported.
The SAM system responds to this need with a hardware and software structure developed using individual adaptable and expandable modules that are easily upgradeable. In particular, the SAM system's gateways are built on a motherboard to which other boards or modules can be attached according to the technological requirements.
Reliable and targeted maintenance tools
The SAM system uses an intuitive graphical interface that can be customised according to customer requirements, featuring a top-down approach that, starting from an initial general overview, allows the user to drill down to the problem in two or three steps.
The SAM system offers a set of tools that simplifies and speeds procedures for identifying, diagnosing and resolving a problem using a multi-level platform. For example, the system can be managed from:
Possibility of connecting directly to the local gateways to quickly and independently access the information offered by the SAM system
Possibility of sending text messages to mobile phones to quickly notify operators of a need for service
- A central location with complete visibility of all places/sites hosting supervised systems. The information gathered helps to:
- Quickly and intuitively identify a possible faulty component through a top-down search
- Provide suggestions for preliminary activities to circumvent the problem and accelerate the troubleshooting phase
- Reconstruct the past events using windows dedicated to past alarms and a chronological list of events
- Remote control of the supervised entities for a first level of intervention
The SAM system offers a tool for managing active alarms using a ticketing system.
With any alarm generated by a malfunction or generic issue the local RTU sends an alarm to the management and control centre.
The system can then be configured to react to the problem. In fact, it can be programmed to automatically generate a new ticket by:
- Assigning a unique ticket ID code
- Recording a Time Stamp to memorise the sequence of events
- Assigning a maintenance operator based on the type of malfunction and area
- Sending text messages and emails to the appropriate personnel
- Proposing possible solutions
The alarm and its corresponding ticket remain active until the problem is resolved.
Video surveillance integration
The SAM system offers the possibility of connecting to the video surveillance system to provide a support tool for maintenance and troubleshooting.
In case of alarm, the camera covering the affected area can be turned on to investigate the cause of the problem.
